This kit includes the impeller housing along with all the components needed for a full water pump service — impeller, wear plate, and seals — so you have everything in one box and aren’t hunting down individual parts mid-job.\u003c\/p\u003e\u003cp\u003eThe raw water cooling system on an outboard is one of the highest-wear service items on the engine. A degraded impeller can’t move enough water to keep cylinder temps in check, leading to overheating damage that costs far more to fix than a routine pump replacement. Replacing the full kit on a regular service interval is the most reliable way to protect your engine investment.\u003c\/p\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eBest suited for scheduled water pump service on Mercury and Mariner outboard engines. Recommended at every 100 hours or annually — whichever comes first — or any time you notice reduced water flow from the tell-tale, overheating warnings, or after running in sandy or silty water that accelerates impeller wear. Also the right kit when replacing a housing that has cracked or corroded beyond reuse.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIncludes: Impeller, housing, wear plate, and seals\u003c\/li\u003e\n\u003cli\u003eApplication: Mercury \/ Mariner outboard engines\u003c\/li\u003e\n\u003cli\u003ePart number: EMP-46-03638\u003c\/li\u003e\n\u003cli\u003eCross-reference: Mercury 46-03638 series\u003c\/li\u003e\n\u003cli\u003eService interval: Every 100 hours or annually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eAlways confirm fitment against your engine’s model and serial number before ordering — Mercury outboard water pump kits vary by horsepower range and model year, and using the wrong kit is the most common installation error. When installing, never run the impeller dry even briefly; lubricate with dish soap or a water-based lubricant before assembly. Inspect the driveshaft splines and housing mating surfaces for corrosion while the pump is apart — it’s the right time to catch issues that would otherwise require a second disassembly. If you’re unsure of your engine’s exact part number, bring the model and serial number to the parts desk for a fitment check.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564143837220,"sku":"EMP-46-03638","price":78.22,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/e1a6e5f4-b04f-4550-af50-12795ca1fd36.png?v=1784522497","url":"https:\/\/marisolmarine.com\/products\/emp-water-pump-kit-with-housing-mercury-mariner-emp-46-03638","provider":"Marisol Marine Company","version":"1.0","type":"link"}
